they dig one hell of a valve box, I'll post a pic sometime of mine 90" spade that grazed a sch 40 line (of ours) didn't but but close. Worst place I ever had to put a tree was at a house where the gas, sewer, h20 and electric all came togather in a V shape... at the tip of the V a tree was destined, straddling the lines. Wound up digging the 6' deep x 90" across hole by hand(s) tons of fun... then the homeowner decided he didn't like the 30' tall magnolia grandiflora and wanted a white pine instead... had to dig it up (w/ the truck) and do it all over. did bust the gas line on the swap but no prob since i don't smoke (and turned off the gas)

Y'know, the last photo in the first post could be good for educating some homeowners about watering requirements, and the need to account for drought conditions. When the subsoil is completely dried out, it's drawing water from the soil near the surface, so some additional watering is in order.
